Patent number: 11671451Abstract: A secure communication channel is established between network devices separated by an unsecured physical space by dynamically performing server/client resolution based on comparison of unique identifiers of the devices. After a link between a first network device and a second network device is established, the devices exchange start frames in accordance with a network security protocol such as the Media Access Control Security (MACsec) protocol. Comparison logic at the first network device compares a value of a unique identifier of the first network device to a value of a unique identifier of the second network device obtained from the start frame transmitted by the second network device, and vice versa. Based on the comparison, one of the devices assumes a server/authenticator role, and the other device assumes a client/supplicant role. The devices operate in their determined roles to perform an authentication process and thereby establish a secure communication channel.Type: GrantFiled: August 5, 2019Date of Patent: June 6, 2023Assignee: Amazon Technologies, Inc.Inventors: Sanjeev Gupta, Frederick David Sinn, Venkata Satish Kumar Vangala, John Mark Glotzer

Patent number: 10992638Abstract: Technologies directed to network address translation based on logical channels in a shared private network with a single ingress to an ISP and multiple customer devices are described. One method receives a first public IP address assigned to an endpoint device by an ISP. The method creates a sub-interface on a WAN interface and adds a first rule that translates the first public IP address to a first private IP address assigned to the customer STA and a second rule that translates the first private IP address to the second public IP address. The first customer STA creates a second sub-interface between the customer STA and the endpoint device, adds a third rule that translates the first private IP address to a second private IP address assigned to the first endpoint device, and adds a fourth rule that translates the second private IP address to the first private IP address.Type: GrantFiled: June 8, 2020Date of Patent: April 27, 2021Assignee: Amazon Technologies, Inc.Inventors: Burak Varan, Sanjeev Gupta, Ravi Manghirmalani

Patent number: 10200187Abstract: In an optical communications system, the thermal pathway for dissipating heat generated by clock and data recovery (CDR) circuitry of an optical communications module is a separate from the thermal pathway that is used to dissipate heat generated by other components of the module. The CDR circuitry is external to the module and is provided with its own heat dissipation device. Keeping the CDR circuitry external to the module and providing it with its own heat dissipation device decouples the thermal pathway for dissipating heat generated by the CDR circuitry from the thermal pathways used for dissipating heat generated by other components of the module. This results in more effective heat dissipation and better component performance.Type: GrantFiled: March 23, 2016Date of Patent: February 5, 2019Assignee: AVAGO TECHNOLOGIES INTERNATIONAL SALES PTE.
